The apparently entitled man took an aisle seat three rows ahead of her and refused to let anyone sit next to him, she said.

In video taken by Zimmerman, the man is seen with his hands folded behind his head and his feet propped up on someone else’s armrest, while a woman using crutches and several others take photos and glare at his inconsiderate behavior.

“You’re a selfish man,” the woman with crutches can be heard telling him.

“He wanted to sit in the whole row by himself,” Zimmerman told the Post.

According to Zimmerman, the man claimed to be diabetic, and at one point, according to passengers, he dared the flight crew to put him in cuffs and drag him off the plane—an admitted sharp barb at the embattled airline.

However, the crew in Shanghai remained cordial and patient, passengers told the Post.

“He was trying to explain to the crew and captain … because he had points, he felt he deserved an upgrade,” Clark Gredoña, another passenger, told the Post. “So this was his way of getting it.”

But, as is often the way in life, the unidentified man did not get what he wanted, and is seen in the video shouting, “I have a seat here! … Shut up! … Moron.”

According to Gredoña, he also picked on a female passenger.

“I think he called her Hillary. Then he called her a lesbian. I think he called a stewardess ‘sweetheart,’” he said.

The man became “increasingly disruptive when asked to deplane,” to the point that “local law enforcement was called to assist,” a United spokesperson told the Post in a statement.
